Unify assertion for no multiple instances of Reanimated with RNGH (so…

…ftware-mansion#3493)

## Description

See:
software-mansion/react-native-gesture-handler#2174

## Changes

Fixed crashing on symlinks with filtering files before executing
operations on them, added property `disableMultipleInstancesCheck `
(possible to specify in `gradle.properties` of **rootProject**) which
allow application to disable the feature.

Note that this property is shared with `react-native-gesture-handler` -
so if someone sets `disableMultipleInstancesCheck=true` the assertion
won't run for neither `react-native-reanimated` nor
`react-native-gesture-handler`.

## Test code and steps to reproduce

Works fine on `TestsExample` application in `react-native-screens`
repository.

## Checklist

- [ ] Included code example that can be used to test this change
- [ ] Updated TS types
- [ ] Added TS types tests
- [ ] Added unit / integration tests
- [ ] Updated documentation
- [ ] Ensured that CI passes
